Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a focusing method for a projection device, where a remote controller of the projection device is provided with a focusing key and a focusing indicator light, and the focusing method includes:
s11: receiving a focusing key trigger signal, starting a focusing timer and starting a focusing indicator lamp, and sending an automatic focusing instruction to the projection equipment to enable the projection equipment to carry out automatic focusing;
s12: detecting whether other key trigger signals are received or not during the time that the focusing timer is not expired;
s13: if so, sending a manual focusing instruction to the projection equipment to enable the projection equipment to carry out manual focusing, and restarting a focusing timer; or sending an automatic focusing exit instruction to the projection equipment to enable the projection equipment to exit automatic focusing and closing the focusing indicator light;
s14: if not, when the focusing timer is up, sending an automatic focusing exit instruction to the projection equipment so that the projection equipment exits automatic focusing, and turning off the focusing indicator lamp.
Specifically, the projection device is started, the user operates the remote controller, the remote controller program judges whether the user presses the focusing key, and here, the remote controller program can also be adopted to judge whether the user presses the focusing key for a long time, for example, the remote controller program judges whether the user presses the focusing key for more than 2s, if the pressing time exceeds 2s, the remote controller starts a focusing timer, the focusing indicator lamp is controlled to be turned on, meanwhile, an automatic focusing instruction is sent to the projection device, and the projection device starts automatic focusing after receiving the automatic focusing instruction. The sent automatic focusing instruction can be a focusing key value, and the projection equipment starts automatic focusing after receiving the focusing key value; the focusing key value can also be converted into a preset key value and then sent to the projection equipment, and the projection equipment starts automatic focusing after receiving the preset key value, wherein the focusing key value only needs to be correspondingly arranged at the remote controller end and the projection equipment end. The long press and the short press of the focusing key are calculated by the remote controller according to the press time of the user finger, and when the finger is released, the remote controller determines what key value is sent to the projection equipment according to the detected press time. Thus, one key of the remote controller can be defined into different functions according to long pressing and short pressing. The focusing key can be a multiplexing key, the long-time pressing of the focusing key triggers automatic focusing, the short-time pressing of the focusing key triggers a setting key, the logic of the remote controller is realized, and a key value is sent to the projection equipment once after the key value is confirmed. After receiving an automatic focusing instruction (key value), the projection device focuses according to the definition of the camera, the motor and the projected image, and the rotation direction may be counterclockwise rotation or clockwise rotation, or may be first counterclockwise rotation and then clockwise rotation, or may be first clockwise rotation and then counterclockwise rotation.
Specifically, after the remote controller starts a focusing timer and turns on a focusing indicator lamp, and sends an automatic focusing instruction to the projection equipment, a user can interrupt automatic focusing by pressing a manual focusing key in a period when the focusing timer is not reached, and perform manual focusing, that is, the remote controller sends a manual focusing instruction to the projection equipment to enable the projection equipment to perform manual focusing, and restarts the focusing timer; the user can also press other keys except the manual focusing key to quit automatic focusing, namely the remote controller sends an automatic focusing quitting instruction to the projection equipment to enable the projection equipment to quit automatic focusing and close the focusing indicator light; if the user does not press any key when the focusing timer is up, the user quits when the focusing timer is up (overtime), namely the remote controller sends an automatic focusing quitting instruction to the projection equipment to enable the projection equipment to quit automatic focusing, and the focusing indicator lamp is turned off.
It should be noted that, as shown in fig. 2, the remote controller of the projection apparatus is further provided with a first key and a second key; the method for sending the manual focusing instruction to the projection device to enable the projection device to perform manual focusing in S13 and restarting the focusing timer includes:
s131: receiving a first key trigger signal, generating a first manual focusing instruction, restarting a focusing timer, and sending the first manual focusing instruction to the projection equipment so that the projection equipment controls a tilt motor to rotate and focus in a preset first direction;
detecting whether other key trigger signals are received or not during the time that the focusing timer is not expired;
if so, sending a manual focusing instruction to the projection equipment to enable the projection equipment to carry out manual focusing, and restarting a focusing timer; or sending an exit manual focusing instruction to the projection equipment so that the projection equipment exits manual focusing, and closing a focusing indicator light;
if the command is not received, when the focusing timer is up, sending an instruction of quitting manual focusing to the projection equipment so that the projection equipment quits manual focusing, and closing a focusing indicator light;
s132: receiving a second key trigger signal, generating a second manual focusing instruction, restarting a focusing timer, and sending the second manual focusing instruction to the projection equipment so that the projection equipment controls the axis-shifting motor to rotate and focus in a preset second direction;
detecting whether other key trigger signals are received or not during the time that the focusing timer is not expired;
if so, sending a manual focusing instruction to the projection equipment to enable the projection equipment to carry out manual focusing, and restarting a focusing timer; or sending an exit manual focusing instruction to the projection equipment so that the projection equipment exits manual focusing, and closing a focusing indicator light;
if the command is not received, when the focusing timer is up, sending an exit manual focusing command to the projection equipment to enable the projection equipment to exit manual focusing, and turning off a focusing indicator light.
Specifically, after the projection device enters the automatic focusing, a focusing timer is started, and the user may interrupt the automatic focusing by pressing a manual focusing key, for example, pressing a volume up-down key or a left-right key of a remote controller to perform manual focusing, during a period when the focusing timer is not reached. The first key may generate the same instruction corresponding to 1 key, 2 keys or multiple keys, the second key may also generate the same instruction corresponding to 1 key, 2 keys or multiple keys, where the 1 key, 2 keys or multiple keys correspond to the instruction composed of key values, the corresponding instruction includes one or more of key values and special codes, the special codes may be binary digits, such as 001 binary system, representing one key, and 010 representing two keys. For example, when a user presses a volume reduction key or a left key, the remote controller generates a first manual focusing instruction and sends the first manual focusing instruction to the projection equipment, and the projection equipment receives the first manual focusing instruction and controls the focusing motor to rotate left; when a user presses a volume plus key or a right key, the remote controller generates a second manual focusing instruction and sends the second manual focusing instruction to the projection equipment, and the projection equipment receives the second manual focusing instruction and controls the focusing motor to rotate right; and when the user feels that the focusing is clear enough, the remote controller stops operating, the remote controller stops generating the manual focusing instruction, and the corresponding projection equipment also stops manual focusing. Here, focusing is a principle that a motor drives a focusing gear of an optical machine to rotate, and is only used for describing remote controller triggering logic.
Specifically, when entering manual focusing, a focusing timer is restarted, and when the focusing timer is not up, whether other key trigger signals are received or not is detected, for example, the set duration of the focusing timer is 5s, if it is not detected that a user presses any key within 5s, a quit manual focusing instruction is sent to the projection equipment to enable the projection equipment to quit manual focusing, and a focusing indicator lamp is turned off, wherein the quit manual focusing instruction sent to the projection equipment can be a preset key value or a preset key value plus a special code, if the user presses a first key or a second key within 5s, the manual focusing is continuously carried out and the focusing timer is restarted, if the user presses any key except the first key and the second key within 5s, the quit manual focusing instruction is sent to the projection equipment to enable the projection equipment to quit manual focusing, the focusing indicator lamp is turned off, wherein the quit manual focusing instruction sent to the projection equipment comprises the key value of the corresponding key or the key value plus the special code corresponding to the key, when the manual quit manual focusing instruction is sent to the projection equipment, the focusing indicator L is turned off, and the manual focusing indicator lamp is turned off after the manual focusing indicator lamp is turned off, and the remote controller is turned off again.
It should be noted that, as shown in fig. 3, the method for sending the exit autofocus instruction to the projection device in S13 to cause the projection device to exit autofocus, and turning off the focus indicator light includes:
s133: and receiving other key trigger signals except the first key trigger signal and the second key trigger signal, sending the key value of the key to the projection equipment to enable the projection equipment to exit automatic focusing, and turning off the focusing indicator light.
Specifically, the remote controller sends an auto-focus instruction and starts a focus timer, and if a user presses other keys except a first key and a second key (a manual focus key), the user exits from the auto-focus, that is, sends a key value of the key to the projection device to enable the projection device to exit from the auto-focus, and turns off the focus indicator lamp. For example, if the user presses the number "5" key, the remote controller may send the key to the projection device, and the projection device exits from auto-focusing, and the focusing indicator light on the remote controller is turned off.
It should be noted that the method for sending the exit manual focusing instruction to the projection apparatus in S131 and S132 to cause the projection apparatus to exit manual focusing and turn off the focus indicator lamp includes:
and receiving other key trigger signals except the first key trigger signal and the second key trigger signal, sending the key value to the projection equipment to enable the projection equipment to quit manual focusing, and closing the focusing indicator lamp.
Specifically, the remote controller enters manual focusing and starts a focusing timer, when the focusing timer is not reached, if a user presses other keys except a first key and a second key, the key value is sent to the projection equipment to enable the projection equipment to quit the manual focusing, and the focusing indicator lamp is turned off, if the user presses the first key or the second key (the manual focusing key), the manual focusing is continued and the focusing timer is restarted, namely, the focusing timer is restarted each time the first key or the second key (the manual focusing key) is pressed. And if the focusing timer is up and the trigger signal of any key is not received, sending an exit manual focusing instruction to the projection equipment to enable the projection equipment to exit manual focusing, and turning off the focusing indicator lamp.
The method comprises the following steps that a key triggering mode of a remote controller is adopted, a user presses a focusing key of the remote controller to trigger automatic focusing, an automatic focusing instruction is sent to projection equipment, a focusing indicator lamp (L ED indicator lamp) is turned on, a focusing timer is started, a volume increasing and decreasing key or a left key and a right key are set as manual focusing keys during the time that the focusing timer does not arrive, left and right focusing can be conducted, any other key except the manual focusing key is pressed to quit automatic focusing, automatic focusing is quitted if no key is operated when the focusing timer arrives, and the focusing indicator lamp is turned off.
The advantages of the present application include: (1) the remote controller focusing mode can be timed by the focusing timer, namely an overtime exit mechanism is adopted, so that the defect that the deflector rod forgets to recover after being moved to the right side in the deflector rod focusing mode is overcome. (2) The user is also visually informed of the current state by the on/off of the focus indicator lamp. (3) If the user uses manual focusing before timeout, the timeout time is recalculated, so that the user experience is consistent. (4) The switching between the automatic focusing state and the manual focusing state is realized, and more function definitions are realized through a small number of keys.
